The vasodilator niacin may provoke greater facial flushing and other symptoms of anxiety in patients with social anxiety disorder than in non-anxious controls. To determine whether this also applies in non-clinical samples, niacin (100mg) or placebo was administered double-blind to 33 young adults and flushing was investigated in relation to fear of negative evaluation (a cardinal feature of social anxiety). Increases in facial blood flow were greater in people with high than low fear of negative evaluation in the niacin condition, but were similar in both groups in the placebo condition. However, changes in pulse rate and ratings of embarrassment, anxiety, blushing and facial heat were similar in both groups in both drug conditions. These findings suggest that the facial vessels of people with a heightened fear of negative evaluation are particularly responsive to niacin under conditions of low anxiety and embarrassment.

Expecting to blush is a common source of social anxiety, and is associated with heightened perceptions of blushing and embarrassment. To assess whether sensory cues associated with heightened facial blood flow are an additional source of anxiety, the vasodilator niacin (100mg) or placebo was administered double-blind to 33 participants, and facial blood flow was investigated when they sang a children's song. Vasodilatation during singing was greater in the niacin than placebo condition, and niacin-evoked flushing and increases in pulse rate were greater in participants with high than low fear of negative evaluation. Nevertheless, ratings of embarrassment, anxiety, blushing and facial heat were similar in both drug conditions. This dissociation implies that cognitive appraisals or negative affect overrode more subtle physiological cues of blushing during embarrassment. Clarifying how judgments about blushing are made could be crucial for correcting faulty assumptions about blushing in people who are frightened of this response.

Rosacea is one of the most commonly occurring dermatoses treated by dermatologists. There are multiple therapeutic options available for the treatment of papulopustular rosacea. Rosacea is an inflammatory condition, classically presenting with flushing and/or blushing along with erythema, edema, telangiectasia, papules, pustules, and nodules of the face. Minocycline, a member of the tetracycline family, has demonstrated benefit in the treatment of inflammatory lesions in patients with rosacea. This manuscript highlights the use of a new sustained-release low-dose minocycline 45 mg tablet, with or without azelaic acid, for the treatment of papulopustular rosacea.

The flush that develops during whole-body heat stress depends partly on prostaglandins production in the skin. Variations in the strength of this local mechanism may contribute to individual differences in susceptibility to blushing and associated anxiety. To investigate this in the present study, the anti-inflammatory agent ibuprofen (which blocks prostaglandins formation) was applied topically to a small area of the cheek in 16 participants with a fear of blushing and in another 14 without this fear. Changes in skin blood flow were monitored at the ibuprofen-treated site and at a mirror image control site while participants sang (to induce embarrassment and blushing) and during aerobic exercise (to induce flushing). The topical ibuprofen treatment inhibited increases in cheek blood flow in both groups during both of these tasks. However, increases in cheek blood flow were greater in participants with high than low fear of blushing immediately after exercise. These findings suggest that prostaglandins contribute to dilatation of facial blood vessels both during emotional arousal (embarrassment) and aerobic exercise. Furthermore, fear of blushing may be associated with mechanisms that delay the resumption of normal vascular tone after a period of vasodilatation. Whether topical ibuprofen gel is suitable for intermittent or long-term use as an aid for blushing control requires further investigation.

Erythematotelangiectatic rosacea presents as persistent erythema and telangiectasia with frequent flushing and blushing on the facial and extrafacial skin. Additionally, papulopustular rosacea shows acneiform papules, pustules, and nodules with persistent plaque-form edema. Despite garnering only grade-C or -D level recommendations, a 585-nm or 595-nm flashlamp-pumped pulsed-dye laser can be considered as an effective therapeutic modality for the treatment of rosacea in patients who are refractory to topical and/or systemic treatments. In this report, treatment with a Q-switched 595-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser with low non-purpuragenic fluence proved to be safe and effective in treating early-stage erythematotelangiectatic rosacea in two female Korean patients. Laser treatment for rosacea was delivered with the settings of pulse energy of 0.4-0.5 J/cm(2), pulse duration of 5-10 ns, 5-mm spot size, 5 Hz, and 500 shots. Additionally, we found that remarkable therapeutic effects were achieved for both rosacea and melasma by combining Q-switched quick pulse-to-pulse 1,064-nm Nd:YAG and Q-switched 595-nm Nd:YAG laser treatments, which required only the changing of handpieces equipped with solid dye. In conclusion, we suggest that treatment with a Q-switched 595-nm Nd:YAG laser with low fluence may provide an additional therapeutic option for treating early-stage erythematotelangiectatic rosacea.

Rosacea is a chronic skin condition characterized by persistent central facial erythema. To explore the burden of illness of rosacea in US adults, a cross-sectional web-based survey was conducted. Participants answered questions on sociodemographics, clinical characteristics, bothersome symptoms, coping and avoidance behaviors, self-perceptions, and health care resource utilization, and completed 2 quality of life instruments, the 21-item rosacea-specific quality of life questionnaire (RosaQoL) and the 36-item Short Form Health Survey (SF-36). This paper reports the data from the 409 respondents with erythematotelangiectatic rosacea (ETR), analyzed by erythema severity. Mean age was 53.1 years; mild, moderate, or severe erythema was reported by 63.6%, 32.0%, and 4.4% of participants, respectively. Blushing/flushing and bumps/pustules were the most bothersome symptoms across severity subgroups. Participants in all subgroups coped with rosacea by applying make-up and managing their stress and anxiety, and tried to prevent rosacea flares by avoiding sun exposure, specific skin care products, and other triggers. Self-perceptions differed by severity subgroup: satisfaction with facial appearance significantly decreased, and worrying about how people will react and feelings of unattractiveness to others significantly increased, with greater erythema severity (all P less than 0.01). Treatment or assessment of rosacea was sought by 20% of participants in the past 3 months, most commonly from a dermatologist. Metronidazole was the most frequently prescribed topical product across severity subgroups, whereas doxycycline and other oral antibiotics were prescribed most frequently in the severe erythema subgroup. RosaQoL emotional domain scores increased with erythema severity (P equals 0.0035), but none of the SF-36 domain scores differed significantly by erythema severity. These results demonstrate that rosacea is associated with a substantial burden of illness that spans all levels of erythema severity in patients with ETR. Feelings of unattractiveness and the adverse impact of rosacea on emotional quality of life increased with erythema severity. J Drugs Dermatol. 2018;17(2):150-158.
